Is ketchup (high fructose corn syrup, united states) low FODMAP?

The name of the sweetener does not identify the group that determines this finished ketchup’s rating. Fructans are the elevated group at the two larger volumes; all other displayed groups are low. This comparison belongs to the specific US formulation and cannot rate every ketchup containing corn syrup.

Ketchup (high fructose corn syrup, United States) and IBS: what to know

When noting a meal in an IBS diary, include ketchup added at the table as well as sauce already inside a burger or sandwich. Repeated small squeezes can make the total hard to estimate. Record the condiment amount separately from the food it accompanies rather than assigning the whole meal this rating.

Gut-friendly ways to eat ketchup (high fructose corn syrup, united states)

Measure the ketchup into a small dipping dish before eating. For a shared recipe, record the total volume added and how the finished dish is divided. A marked measure is clearer than an informal squeeze or heaped spoon. Compare sucrose-sweetened ketchup using its own volumes rather than assuming a different sweetener creates an identical serving.

Frequently asked questions

Is ketchup with high fructose corn syrup low FODMAP?

The matching US ketchup is low at 18 ml. Increasing the amount to 20 ml or 24 ml changes the rating to moderate or high.

Can I use one ordinary tablespoon?

The entry’s tablespoon description refers to 20 ml, which is moderate. Spoon capacities vary, so measure the stated millilitres.

Does adding water make more ketchup low FODMAP?

Water changes the mixture’s volume, not the amount of original ketchup it contains. Track the ketchup volume used in your portion.
